To all whom it may concern:

Be it known that I, ROY RrTTENHoUsE, a citizen of the United States of America, residing at llVormlevshurg, in the county of Cum herland and State of Pennsylvania, have invented certain new and useful improvements in a Combined Car and 'lh-ain-Pipe Coupling, of which the following :1 specification.

This invention relates to couplers dofor use in opernt-ing the train pipe mil train p cormlers.

V of this invention is to provide novel 2 ling the ear and simultm'ieoi ly disconnect ig the flexible pipes of the on; brake suppl'" and the invention also contemplates the g vision of means for operating a valve of the train pipe of the air brake suit-em.

With the foregoing and other objects in view, the invention consists in the details of construction and in the arrangement and emnbinnliion of parts to be hereinafter more fully set forth and ciain'icd.

lo desrribing the invention in detail, rel"- will be had to the accompanying wings forming part of this specification oruin like characters denote corresponding er in the several views, in which Jigure 1, is a view in perspective of the front end of a car with the i'l'ivontio'n applied them-rte; i2, is an end view of a bracket in which the operating shaft mounted is" 3, is a detail. view of a bell, crank lever; his. 4, is a detail view ol' the valve operating wrenrh. Fig. is a Z HH'SpBChlVL view showing); the application of a midilied arrange- 1 vitl 1. r a r a operating toe on. p-

' '5, and part i in rating or =g th arm .us neg the pin from v head or allowing itto he returned to opera v position with relation to the tailf the knuckle c.

i rially rotatable in the bearings is angular in cross section in order that the arm E, and another arm Gr, may be applied thereto and take motion therefrom.

The arm G, has a link g, on its and con nected to one member H, of a bell crank'lever I, and the member 7!, of the bell crank lever is provided with a yoke J forming a seat for the hose or flexible end K, of the train pipe. The voke J, is provided with a shank j,-litted in an aperture of the member h, of thebell wank lever and said shank is retained in place by the cotter pin j. i

The train pipe L, has a valve with a valve stem M. but said valve stem is engaged by the wrench N, which wrench is journaled in the bearing n. applied to the frame of the car. The upper end of the wrench is provided with a toothed segment 0, and the said toothed segment engages the teeth of the rack ,l. which rack is applied to the operatingshaft F. The shaft l is mounted to partially rotate and reciprocate in its bearing and the reciprocal motion of said shalt when the rack P, is in engagement with the toothed segment will result in partial turning; of the wrench N, and ermscquontly partially rotating the valve stem. It is through the manipulation of the shaft l that the air supply is controlled through the mediumof the valve.

In operation, assuming that the cars are coupled and the air pipes are connected, movement of the shaft longitudinally of its axis would result in partial rotation ol the train pipe valve which movement is sullicient to close the valve. Partial rotation of the shalt F, would then result in elevating the ronpliny; of the train pine so that it would be disconnected from a section of the coupler on the opposite car. mont would be communicated to the pin 1), through the arm E, and the flexible connection d, and the coupler would be free to open as the cars moved apart. A reverse move ment oi the jiarts just described will result in returningthe pin to its operative position. in the draw-l1ead and the train pipe coupling would descend to be engaged by the con ,0 'ng member on the other car. The bracket m 18 applied to the frame of the car and is designed to support the central portion of the shaft F. The said bracketdoes not completely embrace the shaft but is 0 Jen at the top so that the migular portion of t 1o shaft F, will freely rotate therein. The bracket has cut-away portions (1, to receive the inner ends of the arms E and B.

At the same time, riTLove- In the modification shown in Fig. 5, A, indicates the car frame, f, a bearing, and F, a shaft which parts are similar in all respects .to the car frame A, bearingf, and shaft F, heretofore described. In this modification the rack I, is omitted and a hook 1, is applied to the shaft F, said hook engaging a-lever 2, which lever is pivoted to a bracket 3, at tached to the car frame. The lower end of the lever extends through a slot 5, in the crank 4, which crank is mounted on the stem 6, of the valve applied to the train pipe L, which train pipe has the usual flexible coupling K. i

I claim 1. A coupler and train pipe operating mechanism comprising a shaft, arms thereon, a toothed rack on the shaft, a toothed segment engaged by the rack, a train pipe valve operating device actuated by the toothed segment, a train pipe coupler, a car coupler, and means for controlling the train pipe coupler and car coupler at a single operation.

2. In a car and train pipe coupler, a train pipe having a valve, means for operating the valve, a toothed segment on the valve operating means, a shaft, means on the shaft for engaging the toothed segment to partially rotate it, means for supporting the train pipe coupling and means for controlling said support.

3. In a car and train pipe coupler, a shaft on the frame of the car, an arm extending therefrom, a bell crank lever mounted in bearings on the frame of the car, a link connecting the arm and one member. of the bell crank lever, and means on the other member of the bell crank lever for engaging a train pipe coupler.

4. In a car and train pipe coupler, a shaft journaled on the frame of the car, a bell crank lever, means on one member of the bell crank lever for supporting the train pipe results in the oscillation of the bell crank lever.

5. In a car and train pipe coupler, the combination with. the air sup 1y pipe, of an air brake system, a valve in the pipe, means for opening and closing the valve, a toothed segment on the means for opening and closing the valve, a toothed rack engaging the segment, a shaft on which the toothed rack is mounted, and means for mounting the shaft to permit reciprocation thereof.

6. In a car and train pipe coupler, the combination with an air supply pipe, of an air brake system, a valve in the pipe, a shaft mounted to slide transversely of a car, a lever operated by the shaft, a valve in the train pipe, and means whereby the movement of the lever operates the valve.

7. In a car and train pipe coupler, a train pipe having a rotating valve and a coupler mounted on the car, a shaft, and means connecting the shaft to the valve and the coupler whereby a rotating and sliding movement of the shaft will simultaneously operate the valve and coupler mechanism.

8. The combination with a car, of a car coupler carried thereby, means connected to the coupler to uncouple the car, a hose extending from the car having a coupling head which will uncouple when raised, and means connecting the free end. of the hose to the uncoupling means to raise the head.

'9. The combination with a car provided with a car coupler of the Janney ty ie, an air hose having a coupling head of the vestinghouse type, and means connected to the car coupler and the air hose adapted to operate the coupler and the air hose to uncouple them su )stantially simultaneously.

In testimony whereof I affix mysignature in the rcsence of two witnesses this th day of pril, 1908.
